SODA-VATER DRAFT.

Application filed July 21,

T 0 all whom. t maj concern:

Be it known that l, ROBERT M. GREEN, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented Soda-Tater Draft, of which the following is a. specification.

The present invention relates to a soda water draft used for dispensing' carbonated water. and one of the objects of said invention is to provide a device of this character in whichthe volume and speed of the stream of carbonated water discharged may be. controlled by a simple and easjv movement of the operatingy handle in a single plane and in a single direction.

A further object of the invention is to provide a soda water draft in which there are a plurality of valves controlling the speed and volume of the water and whose construction shall be suc-h that they may he operated by a singley movement of the operating handle; the device including means for insuring the proper seating of the main valve and for preventing; subsequent leakage.

I also desire to provide novel means for holding the operating handle in one of its displaced positions to permit a Continuous flow of the water, and which retaining' means maj: be readily released when the flow of water is to be restricted or entirely cut olf.

Another object is to provide a soda water draft with a novel arrangement of fluid passages and valves, which will operate to cause a gradi'ial cutting olf of the flow of water.

These objects and other advantageous ends, I attain as hereinafter set forth, reference being had Ato the accompanying drawings.Y in which.

Fig. l is a vertical sectional view of a soda water draft constructed in accorda-nce with my invention; and Y Figs. 2 and 3 are vertical sections similar to that of Fig. l, showing the operating parts in positions to deliver a, large slow stream and a tine rapid stream respectively.

In the above drawingsi l indicates va pipe leadine' from a carbonated water tank and threaded into a part 2 of the draft appa.- ratns. An opening; e permits communication hetween the pipe 1 and the interior of the draft apparatus. and a needle valve 3 is mounted within the portion, 2 in. position 1921. Serial No. 486,457.

to be projected across the opening 4 to restrict or regulate the flow of water to the draft apparatus. The needle valve 3 is threaded into a suitable sleeve 5, which is in turn threaded into the part 2.

The inlet portion Q carries at its opposite end a fixed casing` (n having a partition (3 and containing the valve for controlling the discharge of carlionated water. Said partition has an axial passage of which one part 6 is slightly smaller in diameter than a ser-ond part (SC, and its opposite faces are shaped to form valve seats G' 6e. The upper end of the casing' (3 is closed b v a removable cap `T and is surrounded by an outer movable` casina' 5% having` openings 9 in its lower face. The inlet portion 2 projects through a slot lO in the casing` S and this slot is of a length sufficient'. to permit mov-ement of said casing' while said portion 2 and the inner casing 6 remains stationary. The upper end of the casing 8 is closed b v a threaded cap l1` having an axial opening 'l2 in which is mounted ahollow flanged plufz 13 whose body eloselj7 tits and projects out of the smaller portion 1Qy of the opening' l2. The up "ard movement of the plug' is limited b v the flange 133.

A A. plug' l'df is 'threaded into the lower portion of the opening 12h and its lower face shuts upon the upper face of the cap 7 when the parts are in the in= perative positions shown in Fig. l so that it acts as a stop for the outer casing SlA By adjustingthe plug' Ll up or down. the position or rest of the casing 8 may he regulated as desired.

coil spring l5 is mounted within the plug' 13 so as to act between it and the plug l-l and to normallf.7 project said plug' 13 through the' top of the cap il to the limit permitted bj' the flange 13a.

An operating handle i6 with a head 16 has two arms 17 with forked lower ends 17a mounted on pivot pins 18 projecting from the outer casino` 9. These arms 17 have rear extensions 17" pivotall)Y mounted upon a pin 19 carried b v a projectingr portion of the part 2.

A screw 2O is mounted in he operatingT handle 16 between the arms i7 in position to engage the top surface of the plugr when said handle is in its inoperative position (Fig. l) and upon movement of the handle from. the position of Figa' l. said screw will disengage the plug; which will he projected outwardly through the cap l1 to the position shown in Figs. 2 and 3.

lf it is desired that the operating;r handle remain in the discharge position ot' Fig. 2, the operator may remove vhis hand and the screw 2O attached to the handle will he retained against the plug 13. lVhen the handle is moved towards its normal position` thevserew 2OI will ride upon the plug 13 and force it downwardly against the action of the. spring` l5.

Vithin the casing' 6 is a check valve 2l having a body portion 2la surrounded hy a coiled spring' 23 which maintains it in proper vertical alignment and the lower tace of said valve is recessed Jfor the reception ot a washer 22 adapted to cooperate with the valve seat 6d surrounding the upper end ot the passage 6b. A screw 24 is threaded into the valve 2l and has a head 24 formed with a transverse slot 24J.

A poppet valve 25 has a stem 25a looselyY movable within the passage (Sc and termed tol closely tit the passage Gb: its upper end being convexlv curved and designed to cooperate with the slotted 'tace ot the screw head 24.1". The valve 25 is flanged approximately midway oi its length and the upper 'tace of the flange has a recess Jfor a packing' 'asher 26 positioned to engage the valve seat 6e formed around the lower end ot the passage 6". The lower end ot the valve 25 is ot reduced diameter and projects through an opening 2S in the bottom face ot the outer casing. A shoulder 25b on the lower end ot the valve, rests upon the inner surface of the lower edge of the casing, to limit the downward movement of the valve 25, and also to transmit movement to it from the outer casing. A passage 29 is termed through the center ol the valve and has a restricted portion 3() at its lower end.

Under normal conditions the parts are in the inoperative positions shown in l? l. with the valve 21 seated on the valve seat 6d closing the passage 6b and the valve 25 in its lowest position with its shoulder 2 resting on the bottom end ot the casinpr S. Then it is desired to deliver carbonated water` the handle 1G is moved 'from the position of Fig. l to that shown in Fig. 2, causing an upward movement of the outer casing 8 and of the valve 25. During such upward movement the stem will engage the screw 24- ot the valve 2l and cause an upward movement ot the latter against the action ot the spring` 23. thereby movingr said valve 2l from its seat 6 and openingT the passage 6h. Carhonated water will now tlow troni the inlet -l through the passages t3" and tic around the stem 25"L and out through 'the deliver)v openings The operatingr handle ma)v` he allowed to remain in the position shown in Fig. 2 with the 'full liow ot water discharging, since the screw-20 engages the 65 retaining` plug 13. This arrangement is partictdarlvv advantageous when a continu-y ous How ot' water is desired without the neeessitv ot the attendant holding the operatingr handle.

Then a sutticient 'liow of water has occurred, and it is desired to ydeliver a tine fast stream, the operating handle is moved to the position shown in Fig. 3 thus causing a further upward movement ot the outer casing` S and of the valve 25. Duringr such further upward movement the stem 25L1 will raise the valve 2l further trom its seat, and the upper end ot said stem 2,5n will enter4 and thus close the passage 6",'} 3reventing 8O flow from around the outside of the stem 1When the parts reach the positions of Fig. i5, the washer 26 is seated upon the valve seat tie, and since the slot 24h in the 85 head ot the screw 2st is immediatelyv adjacent the upper end o' the passage a limited amount ot' water will pass through said siot into said passage, through the restricted passage 3() from which it will he. delivered 90 in a line Ytast stream. lVhen itis desired to entirely cut ott the tlow ot water. the operating; handle is moved to the position ot Fig. 1. whereupon the screw 20 rides uponrthe top ot' the plug 13 and toi-ces it into the cap 1l. 95 During` such movement the outer casing 8 and the `,valve 25 will move outwardly while the valve 2l will close the passage 6b. .1

it has heen found in prior apparatus of this cl'iaracter. where the valve was directly 100 connected to an operating means.v or where the valves 21 and 25 were made integral, that the valve 2l would not properlvseat, and would cause leakage at this point. This is entirelyr overcome in the present construction. f

Ry the provision of a rounded tace upon the upper end otl the valve stem 25, there will he a gradual closure ot the passage 6b and consequentlyv a gradual cutting" ot of the water. .Y
